cleaning exterior screens

Even when the weather's nice, outdoor screens get grimy fast—caked with pollen, bug splatters, and that fine layer of road dust. You need a soft microfiber cloth and a gentle soap solution, nothing too harsh or abrasive. Work in sections, don't let the cleaner dry on, and always rinse thoroughly to avoid streaky residue. It's tedious but satisfying: once you're done, the picture looks crisp and bright again, like the screen just woke up.
